Developer Graham M. has released a new sliding edge menu component for Delphi XE8 Firemonkey. The component is similar to the TMultiView component that ships with Delphi XE8 Firemonkey except it may be simpler to use but less flexible. The main different is that the TksSlideMenu component is a non-visual component and you add menu items via code. I think you should be able to use component on Android, IOS, OSX, and Windows. It uses bitmap caching for optimal animation performance. You can specify a menu header with title+image and you can set for fonts, colours, etc. It can slide out from the left or right side of the screen and it has three animations which are push, overlap and reveal. The component is free and the source code is available on Github. You should be able to use this component with Appmethod as well.
